To evaluate the effect of modified phacoemulsification for high myopia complicated with cataract.

A total of 66 patients with high myopia complicated with cataract who visited the Harbin Aier Eye Hospital from March 2019 to April 2020 were selected and divided into control group and observation group by random number table method, with 33 cases in each group. The control group received conventional phacoemulsification, while the observation group received modified phacoemulsification. The visual acuity recovery, corneal endothelial cell count before and after surgery, and postoperative complications of the two groups were compared. χ² test was used for comparison of counting data, t test and repeated measurement analysis of variance were used for comparison of measurement data.

After 6 months, the proportion of patients in the observation group and the control group whose visual acuity recovered to 0.5 or above was 93.94% and 72.73%, respectively. The observation group was significantly better than the control group (χ²=5.346, P < 0.05). After surgery, there was a statistically significant difference in the corneal endothelial cell count between the two groups of patients (F=11.460, P < 0.05), and the corneal endothelial cell count in the observation group was significantly lower than that in the control group at 1 and 3 months after surgery (P < 0.01). After surgery, The incidence of postoperative complications in the observation group was significantly lower than that in the control group (6.06% vs. 33.3%; χ²=7.759, P < 0.01).

Modified phacoemulsification can effectively improve the visual acuity of patients with high myopia and cataract, protect corneal endothelial cells, reduce postoperative complications, which is worth promoting in clinic.
